What is Pig Iron

Pig Iron refers to the metallic product of a furnace that contains over 90% iron. This term arose from the old-fashioned method of casting blast furnace iron into moulds arranged in sand beds in such a manner that they could be fed from a common runner. Because the groups of moulds resembled a litter of suckling pigs, the individual pieces of iron were referred to as pigs and the runner was referred to as a sow. Modern pigs are produced by a continuous pig casting machine.

Pig iron is used in Steelmaking as a high quality source of pure irons units. Demand for pig iron has increased in recent years as Steelmaking operators realise that it offers distinct advantages over other alternate iron sources. Pig iron contains low residuals, produces lower nitrogen steels, has a consistent chemistry, promotes optimal slag conditions and improves process control. Because of the advantages of pig iron it attracts a premium over scrap prices.

Indo Mines plans to become the lowest cost pig iron producer in the world and has already manufactured the first iron ingots from iron sand concentrate using Outotec Ausiron© smelting process.
